1) Insert your SD card into your reader and copy the "private" directory of the Twilight Hack onto it. Also copy the Homebrew Channel "boot.dol" file.

2) Insert the SD card into your Wii and delete your Zelda save file in the Wii File Manager (start a new game if you don't already have one). If you care about your saved game, you can first copy it to your SD card and copy it back after you've installed HBC.

3) Before inserting Zelda into your Wii, flip it over and take note of the text on the inner ring. It will either read "RVL-RZDE-0A-0" or "RVL-RZDE-0A-2" -- both versions will work, but you need to make sure you apply the correct hack (RVL-RZDE-0A-0 requires TwilightHack0, RVL-RZDE-0A-2 requires TwilightHack2, both included in the package).

4) Switch to SD view in your Wii File Manager and copy over your correct version of the hack.

5) Insert your Zelda game disc and start the game. You should see the Twilight Hack save game. Select it to start the game. Once you can control Link, walk backwards (weird, I know) until the Homebrew Channel installer starts. After a minute or two, the HBC will be installed and can be accessed just like any other Channel on your Wii.
